We had bought the tarp to protect our wood furniture. Was supposed to be breathable and waterproof, the manufacturer promises. It was also in the beginning everything was OK. Then came the winter and I could not believe my eyes. The plane has not even held by a summer and has in the rubber cracks everywhere (not in top fabric because everything looks perfect). This all my furniture is moldy. Thanks !!!! We have also left enough air to exchange below. This is simply unacceptable.
